I’m currently practicing employment aptitude tests with a time limit for an upcoming test at an interview and I would like to know what to search for so that I can find some worksheets. The problem is not that they are difficult, just that I am out of practice and so I need some time to go over the math so that I can learn the rearrangement on the calculator by heart as I will have to do so in a timed manner. I can't find anything that I need by googling "algebra questions" or "find x" or "complex missing numbers worksheets". - can anyone tell me what I need to search for to find worksheets with questions like below where I need to find “x”? For example; 63∗8/x+41=55, 17*29+4-x=404, x*12–43+85=246, 984/12–15+x=292, 5*28-x+76=172

There is always a whole number on one side of the bracket and the other side of the bracket always requires the user to find the value of +x, -x, *x or /x. Often with brackets there to confuse. I'm aware it's algebra but its a bit of a niche format.

Googling practice questions for the particular test I'm practicing just comes up with scam sites and the one good resource I have already found -
